Description: With the sloping noses on many of today's cars, it's difficult to judge distance. And SUVs and vans almost take up the entire garage. Park Zone takes all the hassle out of positioning your vehicle. Using sophisticated ultrasonic technology, the sensor unit monitors your vehicle's approach. The display unit, mounted higher for perfect visibility, lets you know how close you are to your pre-set "park zone" by changing from green to yellow and finally red. Park Zone installs in minutes, using only a screwdriver. Uses 4 AA batteries (not included) or plug in the AC adapter (included).

Features:

Sophisticated ultrasonic sensor technology helps guide your vehicle so you know where to stop every time

Although I bought this as a gift for a friend, I have one myself and it works perfectly. The only drawback is the operating temperature. It says you shouldn't use it below 32F0C so you have to take it off the wall and take it inside when it starts getting cold and resort back to the old tennis ball on twine. Otherwise a perfect product. :-}

It was simple to set up. Set one piece at bumper level and the other piece at drivers eye level to see the lights. Either power with an AC switch or batteries. Turn it on with the vehicle parked. Done. Works every time.

This item has performed exactly as advertised, and today's world that doesn't always happen. It has exceeded my expectations relative to its performance and placing my car in the exact same location every time I put it in the garage. It was very easy to install and very easy to calibrate prior to use. I am delighted and think it is a tremendous value for the price.
